This is a handy list of reminders about particular rules, mainly because I forget them.
H2H attacks vs vehicles are worked out at 1 hit per A charactertic
H2H attacks vs a stationary or immobilised vehicle gain a bonus 1D6 on armour penetration
H2H attacks vs vehicles may use any ranged weapon that is not move or fire, ignore sustained fire dice and blast templates
H2H attacks vs exposed crew vehicles are resolved against the crew like normal foot trooper H2H
It takes crew 1 turn to leave their post and take up a new position (chimera gunners!)
